The aim of this work was to synthesize TiC reinforced coating on carbon steel via reduction of ilmenite powder. A mixture of ilmenite and graphite was pre-placed on AISI 1020 steel surface. The effect of the addition of excess graphite amounts on the progress of synthesis of carbide particles was studied. The evolution of phases in different coatings was analysed via X-ray diffraction and scann...

Almost all of the research on cracks in laser cladding is based, at present, a horizontal substrate, which cannot be directly applied to prepare high performance coatings, especially hardness tilted substrate. In this work, influence substrate’s tilt angle crack behavior Ni60A coating studied, based intensity distribution and energy attenuation models Results show that cracking rate (the number...

The pressure and temperature histories on cladding inner and outer surfaces during of LBLOCA (Large Break Loss of Coolant Accident) are considered as boundary conditions for the structural analyses of three cladding materials. Since SiC (Silicon Carbide) has higher yield and ultimate strengths than Zry-4 (Zircaloy-4) under the same primary stresses, SiC has higher primary safety margin than Zry...

Some unavoidable factors in the operating environment could damage single-crystal components of nickel-based superalloys. This work prepared an epitaxial growth NiCoCrAlYTa repaired coating without columnar-to-equiaxed transition (CET) phenomenon on a superalloy by electron beam cladding. The microstructure two cross-sections and surfaces at different depths were characterized. Moreover, format...
